6. Which combination of factors is most likely to produce a large value for the F-ratio and a large value for eta squared?

a.       Small mean differences and small sample variances

b.      Large mean differences and small sample variances

c.       Large mean differences and large sample variances

d.      Small mean differences and large sample variances

7. Which combination of factors will produce a large value for eta squared?

a. small mean differences and small sample variance.

b. large mean differences and small sample variances

c. small mean differences and large sample variances

d. large mean differences and large sample variances

8. When the null hypothesis is true, the F-ratio is balanced so that the numerator and the denominator are both measuring exactly the same sources of variance

a. True

b.False

9. A research report states that there are “significant differences between treatmens with F(2,27)=5.36, p<.05.” Based on this report, you can conclude that the research study evaluated the mean differences for three treatment conditions.

a. true

b. false

10. Post hoc test are used to reduce the risk of a Type I error.

a. true

b. false

Explanation / Answer

Answer to the question:

6.large mean differences and small sample variances

7.small mean differences and small sample variances

8.True

8.True - df numertor= k-1, where k = treatment groups = 3-1=2

9.True - yes, we are reducing the likelihood that a Type I error is present
among the means.
